Advice
Using the ventilation and air
conditioning system
► To ensure that air is distributed evenly, keep the external air intake grilles at the base
of the windscreen, the nozzles, the vents, the
air outlets and the air extractor in the boot
free from obstructions.
► Do not cover the sunshine sensor located on the dashboard; this sensor is used to
regulate the automatic air conditioning
system.
► Operate the air conditioning system for at least 5 to 10 minutes once or twice a month to
keep it in perfect working order.
► If the system does not produce cold air , switch it off and contact a CITROËN dealer or
a qualified workshop.
When towing the maximum load on a steep
gradient in high temperatures, switching off
the air conditioning increases the available
engine power, enhancing the towing capacity.
Avoid driving for too long with the
ventilation off or with prolonged operation
of interior air recirculation. Risk of misting and
deterioration of the air quality!
If the interior temperature is very high after the vehicle has stood for a long
time in the sunshine, air the passenger
compartment for a few moments.
Put the air flow control at a setting high
enough to quickly change the air in the
passenger compartment.
Condensation created by the air
conditioning results in a discharge of
water underneath the vehicle. This is perfectly
normal.
Servicing the ventilation and air
conditioning system
► Ensure that the passenger compartment filter is in good condition and have the filter
elements replaced regularly.
We recommend using a composite passenger
compartment filter. Thanks to its special active
additive, this type of filter helps to purify the
air breathed by the occupants and keep the
passenger compartment clean (by reducing
allergic symptoms, unpleasant odours and
greasy deposits).
► To ensure correct operation of the air conditioning system, have it checked
according to the recommendations in the
Maintenance and Warranty Guide.
Stop & Start
The heating and air conditioning systems
only operate when the engine is running.
Temporarily deactivate the Stop & Start
system to maintain a comfortable temperature
in the passenger compartment.
For more information on the Stop & Start,
refer to the corresponding section.

Safety
Front airbags

This system protects the driver and front
passenger in the event of a serious front impact,
in order to limit the risk of head and chest
injuries.
The driver's airbag is fitted in the centre of the
steering wheel; the front passenger airbag is
fitted in the dashboard above the glove box.
Deployment
They deploy, except the front passenger airbag
if it is deactivated*, in the event of a serious front
impact to all or part of the front impact zone A.
The front airbag inflates between the thorax and
head of the front occupant of the vehicle and the
steering wheel, driver's side, and the dashboard,
passenger's side, to cushion their forward
movement.
* For more information on Deactivating the front passenger airbag, refer to the corresponding section.
Lateral airbags

In the event of a serious side impact, this system
protects the driver and front passenger to
mitigate the risk of injury to the chest between the hip and the shoulder.
Each lateral airbag is fitted in the seat backrest
frame, door side.
Deployment
The lateral airbags are deployed on one side in
the event of a serious side impact applied to all
or part of the side impact zone B.
The lateral airbag inflates between the hip and
shoulder of the vehicle's occupant and the
corresponding door panel.
Curtain airbags
System contributing towards greater protection
for the driver and passengers (with the exception
of the rear centre passenger) in the event of a
serious side impact in order to limit the risk of
injury to the side of the head.
Each curtain airbag is built into the pillars and
the upper passenger compartment area.
Deployment
It deploys simultaneously with the corresponding
lateral airbag in the event of a serious side
impact applied to all or part of the side impact
zone B.
The curtain airbag inflates between the front
and rear occupants of the vehicle and the
corresponding windows.
Malfunction
If this warning lamp comes on in the instrument panel, you must contact a
CITROËN dealer or a qualified workshop to have
the system checked.
The airbags may no longer be deployed in the
event of a serious impact.
In the event of a minor impact or bump at
the side of the vehicle or if the vehicle
rolls over, the airbags may not be deployed.
In the event of a rear or front collision, none of
the lateral airbags are deployed.
Advice
For the airbags to be fully effective,
observe the safety recommendations
below.
Adopt a normal upright sitting position.
Fasten the seat belt ensuring it is correctly
positioned and adjusted.
Do not leave anything between the occupants
and the airbags (a child, pet, object, etc.), nor
fix or attach anything close to or in the way of
the airbag release trajectory; this could cause
injuries during their deployment.
Never modify the original definition of your
vehicle, particularly in the area directly around
the airbags.
After an accident or if the vehicle has been
stolen, have the airbag systems checked.
All work on the airbag systems must only
be performed by a CITROËN dealer or a
qualified workshop.
Even if all of the precautions mentioned
are observed, a risk of injury or of minor
burns to the head, chest or arms cannot be
ruled out when an airbag is deployed. The
airbag inflates almost instantly (within a few
milliseconds) then deflates within the same
time discharging the hot gas via openings
provided for this purpose.

Safety
“ISOFIX" mountings
The seats shown below are fitted with ISOFIX
compliant mountings:


The mountings comprise three rings for each
seat, indicated by a marking:
– Two rings A, located between the vehicle seat
backrest and cushion.


The 2 latches of ISOFIX child seats are secured
to them.
– One ring B, located behind the seat, called
the TOP TETHER, for fixing seats fitted with an
upper strap.


This system prevents the child seat from tipping
forward in the event of a front impact.
This ISOFIX mounting system provides fast,
reliable and safe fitting of the child seat in the
vehicle.
To secure the child seat to the TOP TETHER:
► Remove and stow the head restraint before
installing the child seat on this seat (refit it once
the child seat has been removed).
► Pass the upper strap of the child seat behind the seat backrest, between the head restraint
rods.
► Secure the upper strap hook to ring B.► Tighten the upper strap.
When fitting an ISOFIX child seat to the
left-hand rear seat of the bench seat,
before fitting the seat, first move the centre
rear seat belt towards the middle of the
vehicle, so as to avoid the seat interfering
with the operation of the seat belt.
An incorrectly installed child seat compromises the child's safety in the
event of an accident.
Strictly observe the fitting instructions
provided in the user guide supplied with the
child seat.
For information about the installation
possibilities for ISOFIX child seats in
your vehicle, refer to the summary table.
Recommended ISOFIX child
seats
Also consult the user guide from the child seat’s manufacturer to find out how to
install and remove the seat.
Summary table of locations for ISOFIX child seats
In accordance with European regulations, this table shows the options for installing ISOFIX child seats on vehicle seats fitted with ISOFIX mountings.
In the case of universal and semi-universal ISOFIX child seats, the ISOFIX size category , determined by a letter from A to G, is indicated on the child seat
next to the ISOFIX logo.

Driving
Driving recommendations
► Observe the driving regulations and remain vigilant whatever the traffic conditions.► Monitor your environment and keep your hands on the wheel to be able to react to
anything that may happen any time.
► Drive smoothly, anticipate the need for braking and maintain a longer safety distance,
especially in bad weather.
► Stop the vehicle to carry out operations that require close attention (such as adjustments).► During long trips, take a break every two hours.
Important!
Never leave the engine running in a
closed space without sufficient
ventilation. Internal combustion engines emit
toxic exhaust gases such as carbon
monoxide. Danger of poisoning and death!
In severe wintry conditions (temperature
below -23°C), let the engine run for 4
minutes before moving off, to ensure the
correct operation and durability of the
mechanical components of your vehicle
(engine and gearbox).
Never drive with the parking brake
applied . Risk of overheating and
damage to the braking system!
Do not park the vehicle or leave the
engine running on a flammable
surface (dry grass, dead leaves, etc.). The
exhaust system of your vehicle is very hot,
even several minutes after the engine stops.
Risk of fire!
Never leave a vehicle unattended with
the engine running. If you have to leave
your vehicle with the engine running, apply
the parking brake and put the gearbox into
neutral or position N or P (depending on the
type of gearbox).
Never leave children inside the vehicle
unsupervised.
On flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage to
the engine or gearbox, as well as to the electrical
systems of your vehicle.


If you are obliged to drive on a flooded road:
► check that the depth of water does not exceed 15 cm, taking account of waves that might be generated by other users,► deactivate the Stop & Start function,► drive as slowly as possible without stalling. In all cases, do not exceed 6 mph (10 km/h),► do not stop and do not switch off the engine.On leaving the flooded road, as soon as safety
conditions allow, make several light brake
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle,
contact a CITROËN dealer or a qualified
workshop.
In case of towing
Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
Respect the maximum towable weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the density
of the air decreases with altitude and the
performance of the engine reduces.
New vehicle: do not pull a trailer before
having driven at least 620 miles (1,000
kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
► Distribute the load in the trailer so that the heaviest items are as close as possible to the
axle and the nose weight (at the point where it
joins your vehicle) approaches the maximum
permitted without exceeding it.
Tyres
► Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
► Check the electrical signalling on the trailer and the headlamp beam height of your vehicle.
If a genuine CITROËN towing device is
used, the rear parking sensors will be
deactivated automatically to avoid the audible
signal.
When driving
Cooling
Towing a trailer uphill causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior
temperature. The fan’s cooling capacity does not
increase with engine speed.
► Reduce speed and lower the engine speed to limit heating up.
